CLAW HAMMER Filed April 19, 1932 Patented Nov. 14, 1933 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to aclaw hammer and it has for one of its objects the provision of a hammer for novel claws adapted to pull a long nail without the necessity of putting the usually employed wedge under a hammer in pulling such a nail, and adapted to pull a nail without bending the same.

It is well known that the usual claw hammer, while satisfactory in the former part of the operation of pulling a nail, is unsatisfactory in the latter part of such process, particularly because the usual hammer bends the nail into a curved form. To avoid the bending of the nail, a wedge or block is placed under the hammer. According to my invention, I so construct the claws of the hammer that such a wedge is unnecessary, the claws being adapted, by the use of different parts of the same, to pull a nail straight from the beginning to the end of the pulling operation.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawing which forms part of the application with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therefrom as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claim.

In the drawing:

Fig. 1 is a rear view of a hammer constructed in accordance with my invention, the handle of the hammer being fragmentarily shown.

Fig. 2 is a section taken on line 22 of Fig. 1.

Fig. 3 is a side view of Fig. 2, looking in the direction of the arrow 3.

Fig. 4 is a section taken on line 4-4 of Fig. 2', and

Fig. 5 is a side view of the hammer shown in the operation of withdrawing a nail.

Referring to the drawing for a more detailed description thereof, the numeral 5 indicates the hammer proper mounted on a handle 6. The hammer has a head 7, a handle-receiving portion 8 and claws 9 and 10. The claws are deep and curve around to a position substantially parallel with the handle and each claw has a comparatively free end, as clearly shown in Fig. 3, for a purpose hereinafter mentioned. The claws are separated by a tapered slot 12 which is enlarged at 13 to receive the head of a nail. Extending from the enlarged portion towards the inner end of the slot, there is a ledge 15 formed on the inner face of each claw to receive opposite sides of the head of a nail in the first part of the operation of withdrawing a nail. After the nail has been partially withdrawn, the claws are removed therefrom and the hammer repositioned so that the head of the nail 16, as shown in Fig. 5, contacts with the comparatively broad end surfaces 9a and 10a of the claws 9 and 10, respectively, said surfaces 9a and 1011 being in a plane approaching a right angle relative to the striking face of the head of the hammer but being somewhat inclined thereto so that the head of the nail will not slip off the ends of the claws. Preferably, but not necessarily, the claws are joined at the inner portions of their free ends, as indicated by the numeral 17. i

What is claimed is:

A hammer including a pair of concave-convex claws, there being a generally V-shaped space between said claws, said space being enlarged adjacent the ends of the claws to receive the head of a nail, the inner confronting faces of said claws being formed, adjacent their convex sides, to provide ledges adjoining said space and adapted to engage the head of a nail, the free ends of said claws being broad enough between the convex and concave sides for pulling a nail, there being a V- shaped space between said ends with the larger end of the space being at the convex side of the claws.
